PROBLEM TO BE SOLVED: To provide a composite floor slab made by integrally combining a bottom steel plate and concrete in which the bottom steel plate can be processed with ease and the strength of the floor slab is improved. SOLUTION: In the present composite floor slab 28, floor slab concrete 32 is placed through a coupling means such as dowel reinforcement 31 at the upper face of a rectangular bottom steel plate 29, and slopes 30a, 30b, 30c, 30d lowered toward an outer peripheral direction are integrally molded by cool press along four sides of the bottom steel plate 29. Vertical members 25 and horizontal members 26 are assembled in the pile head 5 of the foundation pile 4 placed in the sea bottom ground 3 to construct a steel beam 24. The composite floor slab 28 is fixedly supported by the steel beam 24. After the panel of the bottom steel plate 29 has been installed, concrete is placed, the bottom steel plate 29 and concrete 32 are unified to construct the composite floor slab 28.
